Here’s a good look at the unit itself for the first time. I’m not sure I’d call it the best looking unit on the market, but I wouldn’t kick it out of one of my cases for being ugly.

As mentioned, the RMX line is fully modular, just like all the other RM units that precede it.

Looking at this view, I wonder if it might not benefit Corsair to have CWT look into getting some darker colored caulk to hold those parts in place. Like the gray stuff used in the AX1500i, for example. This white stuff really shows up when you look through the exhaust grille, and then you get people on message boards asking if something in the power supply melted because there’s all this white goop everywhere.

Both side panels are the same, as we’ve already seen, so I’ll just show you the one side right now.

I am pleased to announce that no modular cable plugs in where it shouldn’t. That’s been an issue for certain units, but Corsair’s been pretty careful to avoid it on their stuff. You can indeed plug in all twelve Molexes and all eleven SATAs at the same time – you will not run out of connectors here. The same goes for the PCI-e cables and CPU cables.

Say what you want about the barbecue look of this fan grille, at least Corsair’s doing something different, here. Most of the high-end EVGA stuff still has those stamped steel grilles, which are inherently noisier than these wire affairs once the fan starts up.

That said, I’m looking on the shelf at the review pile, and I think I see an EVGA unit up there with a wire grille. We’ll take a look at that one in the fullness of time.

As mentioned, this unit is good for full beans at fifty degrees. And you can get every single watt right out of the 12V rail alone if you want. Such are the perks of using voltage regulator modules to run the minor rails off one big 12V output… you can completely unload the minor rails with usually no voltage reading consequences at all.

On to the cables. Corsair still gets that I don’t want Berg connectors on any of the main cables, so they stuck it off on its own adapter.

Of course, the real change from the older RM series is the cabling. To allow for the extra in cable capacitors, the ribbons have been dropped on all but the SATA and Molex chains. I don’t mind that at all. While I do prefer the ribbons for everything but the main ATX (which is a nightmare as ribbon style), traditional sleeving comes in a close second with individual sleeving or individual wires taking a distant third. For me, it’s all about functionality. As long as I can route cables easily, I don’t much care about how they come packaged.

Our ATX cable and both CPU cables each have capacitors in them, so they’re all traditionally sleeved. I like the black on black color scheme too, even if it makes it hard for people to do custom sleeving later. I don’t custom sleeve, so it has no impact on me.

Four PCI-e cables come with the unit, and they all have capacitors too.

All three Molex chains have four connectors each. That’s still really excessive.

On the SATA side of things, two chains have four connectors while the third has three.
